发明名称 RECEIVING APPARATUS AND METHOD AND PROGRAM
摘要 Disclosed herein is a receiving apparatus including a preamble analyzer configured to receive a frame of DVB-T2 made up of an OFDM signal and analyze a preamble contained in the received frame; an offset detector configured to detect a fine offset and a coarse offset on the basis of the analyzed preamble; a carrier frequency corrector configured to execute carrier frequency correction on an OFDM time domain signal obtained by quadrature demodulation on the basis of the detected fine offset and the detected coarse offset; a determiner configured to determine whether the detection of the coarse offset has been completed; and a control signal outputter configured, if the detection of the coarse offset is determined to be completed, to output a control signal for feeding back the fine offset detected on the basis of an OFDM frequency domain signal obtained by FFT computation to the carrier frequency corrector.
